The intake I custom made, the exhust was made between me and a shop. I cut all the aluminum they tig welded it for me. Prop hub is one I had laying around and I cut the flywheel down on my drill press but a shop cut lighten it a bit more. I have a price Id like to get, really depends on what people feel its worth to them but I wont sell it for less the 200.00 the way its pictured.
